Abstract

PURPOSE:To reduce a DC regeneration error of a circuit which discriminates a signal of codes with no DC equilibrium, by interposing a high-frequency and small- gain filter between a DC cut-off circuit and discrimination part. CONSTITUTION:A signal having passed through input terminal 11 and coupling capacitor 12, after passing through filter 16, is DC-regenerated by diode 17 and then discriminated by discrimination part 18. Here, characteristics of coupling capacitor 12 show a high gain at a high temperature and those of filter 16 shows a low gain at a high frequency, so that a DC regeneration error will be zero.
